非线性带强迫项双曲型时滞微分方程解的振动性质

Oscillations of Certain f Hyperbolic Delay Differential Equations with Forced Term

本文研究一类带强迫项时滞双曲型方程解的振动性质．所得应用便利的判别振动的充分条件从理论上揭示了这类方程与普通双曲型方程的差异．

In this paper, we investigate oscillatory Properties at solutions of certain nonlinear hyperbolic parrtial differential equations with forced term and establish a series of criteria. The resuits fully indicate that the oseillations are caused by delay. This is one important conelution and reveals the essential differences between these equations and those hyperbolic partial differential equations without delay.
